■ The LTC®3448 is a high efficiency, monolithic, synchronous
buck regulator using a constant frequency, current mode
architecture. Supply current during operation is only 32µA
(linear regulator mode) and drops to 1µF) supply bypass capacitors. The
discharged bypass capacitors are effectively put in parallel 3448f 12 LTC3448 U W U U APPLICATIO S I FOR ATIO with COUT, causing a rapid drop in VOUT. No regulator can
deliver enough current to prevent this problem if the load …
